OBJ-4.3: Since the database server is part of a critical production network, it is important to work with the business to time the remediation period to minimize productivity losses. You can immediately begin to capture network traffic since this won’t affect the database server or the network (least intrusive) while scheduling a period of downtime in which to take a forensic image of the database server’s hard drive. All network captures and the hard drive should be maintained under the chain of custody if needed for criminal prosecution or civil action after remediation. The server should be remediated and brought back online once the hard drive image has been created.
